Air is blown at the mouth of a tube of length 25 cm and diameter equal to 2 cm open at both ends. If velocity of sound in air is `330 ms^(-1)`, the sound emitted will have all the frequencies in the group

A

330, 990, 1690 Hz

B

302, 664, 1320 Hz

C

660, 1320, 1980 Hz

D

660, 100, 3300 Hz

Text Solution

Verified by Experts

The correct Answer is:
c
Fundamental frequency , `n=v/(2l)=330/(2xx0.25)=660`
Frequency of overtones are
`2n, 3n, 4n, ...=1320, 1980, 2640` Hz
